Any and all 30 A breakers need to be wired with 10 ga copper wire in order to
be safe and efficient. 12 ga wire would work but wouldn't safely power the
circuit because it would quickly reach ( Or be dangerously close ) it's
maximum power transfer capacity which heats up the wire and compromise all the
conductive connections and increase the resistance which would cause excessive
power usage and eventuall create fire hazard.
